E-mini Dow (YM) September (U) contract study: year-by-year results, the day-by-day shape of the move and where highs and lows printed.
Contract Almanac · E-mini Dow
Every September Dow contract 2010–2025, measured over its tenure as the lead contract · Typically leads Jun 12 – Sep 11
The September contract holds the Dow through summer, mid-June to mid-September, and completes the index boards’ summer sweep: 13 of 16 higher (81%), quiet magnitudes, an early bank and a September stall. Across all four indexes, thirty summers in a row of this pattern say the season’s bad name belongs to a different month than the one it wears.
Each year is one contract, measured from the open of the day it took over the lead to the close of the day it handed off, the same roll convention used across all Traders Brief research. An index contract holds the lead for a full quarter, roughly 63 trading days from one roll to the next — these are quarterly seats, not months, and the day counts read accordingly. All highs and lows are the contract’s own trades, marked by trading day of the tenure, not calendar day.
